biology
The stock is the portion of a plant with the root system used in
grafting.
A haplontic animal re productively grows initially by
meiosis, then by mitosis. A diplomatic animal grows by mitosis.
Normally, a homologous pair of chromosomes is required to determine the
outward expression of a trait.
A rhizome is a horizontal stem at or just beneath the surface of the ground which can give rise
roots or stems.
The only haploid cells in an organism are the
gametes.
Cells or organisms having pairs of
homologous chromosomes are diploid.
An architectonic is the egg-producing organ in
lower plants.
When an animal or plant of many cells breaks up into two or more parts, and when these parts survive to produce a
new organism, reproduction occurs by what is known as regeneration.
Approximately 1 year is required in the gymnosperm between
pollination and fertilization. Mitosis is a form an asexual reproduction.
The gametophyte generation of the fern plant produces
reproductive organs which produce a zygote.
All chromosomes in a diploid cell come in matched pairs except the
sex chromosomes.
Cancer is a common disease characterized by
uncontrolled mitosis.
Plants that produce their gametes in flowers are called
angiosperms.
Offspring which arise as a contiguous outgrowth of the parent is known as
budding.
The mismatch of a NDA base pair during duplication can results in a
change or a mutation.
Reproduction by mitosis duplicates
chromosomes, genes, and DNA.
